Multiplying by 10 is simply sliding the decimal one place to the right.
5.2 * 10 = 52
Use mental floss to prevent decay of your morals. ■
You can, if you wish.
70
Multiply 3 times 25 mentally (the answer is 75), and then adding three zeroes will give the total of 75,000.
To find the product of 6 and 741 using mental math, you can break it down by distributing the multiplication. First, calculate 6 times 700, which is 4200, and then 6 times 41, which is 246. Finally, add these two results together: 4200 + 246 equals 4446. Thus, 6 times 741 is 4446.
use mental math
3 x 1 = 3 3 x 2 = 6 3 x 122 = 366
1800
You would multiply 12x5, and then just add a zero. The answer is 600.
The answer depends on the equation. Very few people, if any, can use mental maths to find the value of n in logpi/7(3e) = 95.3. I would not even try!
Mental math! aka in ur head
optometrist use math 36 topics like subtracting adding mental math triangles and much more!
Mental math is basically just giving an estimate of what the value will be, for example: 5x306= 5x3 and add 2 zeros will give you 1500 and the actual answer is 1530 so its kind of like rounding off to the nearest.
